Abstract:
The present invention easily improves the heat transfer characteristics of a mold for a rubber article provided with a rubber molding part formed by sintering a metal powder. A mold (1) for a rubber article is provided with a rubber molding part (10) for molding a rubber article by bringing a contact part (11) into contact with the rubber article, and a holding part (20) for holding the rubber molding part (10). Metal powder is sintered to form the rubber molding part (10). During casting of the holding part (20), part or all of the portion of the rubber molding part (10) excluding the contact part (11) is cast in the holding part (20), and the holding part (20) and the cast part (14) of the rubber molding part (10) cast in the holding part (20) are joined.
